Rhonda is skeptical, but may benefit in some people in situations as more white blood cells are available to help repair injuries, but it still can cause damage too (can also help in those with issues with thei blood brain barrier and struggle to get oxygen into the brain)

Joe Namath is known to use hyperbaric chambers to help with negative cognitive effects of concussions/brain damage from years playing football

Oxygen is required for metabolism which is needed (along with food) to make energy and thus fix things (but can also cause cell damage)

Altitude Training: Current perspective is that it is ideal to live at high altitude (or sleep in tents that mimic it) and train at sea level for athletic results (however, these are not well controlled studies)

Cold to Lose Weight? Can also increase metabolism when cold to potentially lose weight (but likely better to spend more time in cold water immersion vs. short cryotherapy sessions) – See the chapter of The 4-hour body, but Tim Ferriss

Going from very cold to very hot (though common in Nordic countries) may tax the heart, so be careful!

When it breaks down when you are stressed endotoxins enter your blood and can bind with small dense LDL to keep it from damaging you organs/cells (when inflamed you make more LDL)

BUT now the LDL cannot get back to the liver to be recycled and is stuck circulating

So immune system attacks them, but can’t kill them as they are not bacteria/viruses, but release more pro-inflammatory cytokines that make it small and dense which then lead to plaques and are part of CVD

Mucin in gut cells to as the gut cells to keep immune cells from bacteria
